changed documentation
Turned verbose on, so that the errors are a little more useful
Completed geo_x conversions and tests
added test for geo_x channel converters
added observatory, and magnetic north converters, and tests
added vertical components to mag and geo, for f, compf, i, and g
added obspy style comments,  and added generic geo_to_obs type calls for mag and obs
updated to use numpy, added some comments to Test.
removed channel class, functions are now standalone, with d0 passed into needed calls.
Added tests for d0, and comments which include covering how the base functions work.
updated test code to include more comprehensive tests,  and have more readable comments
Updated test calls to include messages
added degree-radian conversions, and increased tests for base converters
changed get_radian_from_decimal and get_decimal_from_radian to work on minutes.  Also incomplete changes in ChannelConverterTest.py
changed radian_to_minutes to radians_to_minutes, and capitalized the constants R2M and M2R.
updated first test, test_get_geo_from_obs, and the test notes.
changed tests to be more readable,  added more complete comments on how components relate.
cleaned up constants
Switched to numpy.testing instead of nose.tools to be able to use the verbose flag in numpy.
