remove r+ read from forcings files
fix minor typo in c_convolve and remove extra astype call in read_forcings
simplification of c_convolve.c
fixes to fraction2domain.bash, double prec fraction and fix to land mask ncap2
Reworked search catchment.

Speed and algorithm improvements:
- Tracks and saves path - either in or out of catchment.
- If new path encounters a point that is out (-1) or in (1), the paths are joined and we break out of the search loop
- Still tracks path length (cells / count_ds) and returns sorted arrays for make_uh computations.

This is likely to have significant speed up implications for large basins.
Fixes to north south indexing convention.

The formalized convention is now: the y-dimension 0-index position
corresponds to the highest latitude.
add better fractions plotting routine.
updates to read forcing and history file unit conversion
Improvements to RVIC parameter file generation processes

- now allows input pour points file to include x and y index locations (0, 0) is nw flow direction domain corner
- now correctly checks for latitude order after remapping
- now includes two new variables in output parameter file (outlet_upstream_area, and outlet_upstream_gridcells)
- fix to VIC flow directions
add fix to make sure outlet names are only ascii characters

Debug make_parameters.py (remove Pandas dropna argument "inplace") and aggregate.py (Point class argument domy instead of gridy)
Merge pull request #4 from tcchiao/master

Small bugs in make_parameters.py and aggregate.py
Update README.md
Update README.md
Fixes bug when y dimension ordering in forcing files does not match the convention used to generate the parameter file

This convention is the zero position in the latitude array should be the maximum value.  This fix flips the domain and paramter file if/when the forcings come in upside down.
Merge remote-tracking branch 'github/master' into feature/check_lat_order
Major reorg of rvic package.

- Moved rvic source files to rvic core package
- Create rvic_model script to be installed in bin/ (usage: rvic_model (rvic_function) config_file ...)
- Added setup.py and travis info
add netCDF zlib compression options to all write functions, default is zlib=False (also gives the option for sigfig truncation and compression level.  Adresses issue #7
