Created a unit test for the lib.geometry.lines.closest_point() function.

Added a unit test for the lib.geometry package __all__ list.

Blacklisted a number of files in the maths_fns package for the package __all__ list unit test.

Improved the base class unit test for the package __all__ list.

Subpackages are now also checked.

Added the package checking unit tests for the lib package.

Created the lib.geometry.lines module for performing geometric operations with lines.

This has one stub of a function lib.geometry.lines.closest_point() which will be used to find the
closest point on a line to a given point.

Created the lib.text package for text manipulation.

The first module will be the text formatting of tables.

Removed the prune parameter from the backend of the monte_carlo.error_analysis user function.

This was a dangerous parameter used to mimic the 'Trim' parameter from the Modelfree4 program. The
result is bad statistics. The probable reason for the 'Trim' parameter was the failure of
model-free models in the simulations, but this issue was solved using model elimination (see
http://www.nmr-relax.com/refs.html#dAuvergneGooley06).
