started spatialvectors.py; have a function to return field values of interest based on intersecting shapefiles; included tests as well
cleaned up print statements in tests
trimming down the testing print statements a lot but creating a nice function called print_test_info() that loops through the expected and actual values and asserts if expected values matchs actual values; this mirrors nose library
in middle of reducing lengthly test statements
finished cleaning tests in watertxt.py
