- also remove references to glue from a few comments
- this removes the only dependence on glue from lalinference
- the conversion from glue.pipeline to lal.pipeline has not been tested.  the glue.pipeline module was never ported to python 3 so anything relying on it has been non-functional for years, and, therefore, is likely also bit-rotted in other ways.  it is left as an exercise to the lalinference developers to restore these codes to a working state if desired.

- knope_utils.py is modified
- this eliminates lalpulsar's only dependence on the glue package
- this patch is untested:  glue's pipeline.py was never ported to python 3, so any code relying on it has been non-functional for years.  this code is, therefore, almost certainly still broken in other ways, and it is left as an exercise for the pulsar group to determine how to repair it if needed.

- this provided classes for the long-ago-deleted ihope pipeline.  no code in lalapps imports this module any longer.
- this module is the only code that references the glue package.  removing it eliminates the only dependency lalapps has on glue.

- remove (very) obsolete reference to glue.ligolw

- no code from glue is imported by code in this package

- from glue to lal

- several classes were removed from the gstlal version because they were not required there.  this patch restores them, because they are needed by lalsuite.
- this patch also adjust pipeline.py's documentation to prevent lalsuite's build from crashing.

- I believe this module originally lived in lalsuite, but when the glue project formed it was migrated there.  In any case, the version that has been in use for as long as anybody can remember has lived in glue.  That module went unmaintained for many years, however, so the gstlal project forked it to have a version that was seeing bug fixes and updates.  The gstlal version, for example, was ported to Python 3.  Now that Python 2 is no longer available, the pipeline.py module in glue is non-functional.
- There remain some users of pipeline.py in lalsuite, for example the sbank pipeline, lalinference pipeline(s?) and the cosmic string search pipeline.  Without access to a functioning pipeline.py these tools are, themselves, non-functional.
- Some people have out-of-tree patches to keep these projects working by converting them to use the version in gstlal.  Those patches cannot be merged, because they would create a cyclic dependency loop between lalsuite and gstlal.
- Therefore, this patch copies gstlal's pipeline.py module into lal.
- Adding it to lalsuite will allow the out-of-tree patches that fix the sbank and cosmic string pipelines to be pushed, which should also remove the only remaining dependency on glue from lalsuite.
- gstlal will be updated to import the module from here after a lalsuite release is available that includes it, so there will not continue to be two forked copies of each other to maintain.

- this is not a verbatim copy.  the following changes are made:
- remove __future__
- remove imports of unused modules
- change __date__ and __version__ imports to get from the correct location
- fix @param entries in documentation so that lalsuite builds.  this is a minimal adjustment to get lalsuite to build.  no effort has been put into updating/fixing/rewriting the documentation.

- I/O code to support a delimited ascii format
- while these are potentially useful, there are not currently any use cases for it, and this particular implementation is based on the obsolete LALStatus-based API and is not being actively maintained.
- the only remaining code in lalsuite to have used these particular functions was lalapps/src/inspiral/calcexpsnr.c (lalapps_calcexpsnr) which as recently removed due to obsolescence.
- after this code is removed, there are other tools elsewhere able to deal with this format if needed.  for example, gstlal provides the tsvdec element to convert two-column ascii text time series into audio streams (and from there it can be whitened, have injections added, be written to frame files, etc.).  numpy can load such a file into a python array object, and, for example, together with lal's series.py can be used to convert two-column ascii psds into xml format.
