Script Name:          bil2mxe.py
Description:          Converts a folder of rasters in the .bil format to the 
                      Maxent .mxe format. 
Date:                 06/03/2019

Usage:
Converts a folder of rasters in the .bil format that can be read by ESRI into 
the Maxent .mxe format. 

This tool assumes that you have created a new folder preferably named 
`input_bil` that holds all of the .bil rasters to be converted. 

This tool will create a new folder named `input_mxe` in the same root folder 
as the `input_bil` folder you provided in the first parameter. This folder will 
hold the rasters converted from .bil format to .mxe format. 

You will see a command window opened by the maxent.jar program that will display
progress of the .bil to .mxe conversion process. Do not close this window, it 
will close on its own when the conversion of all rasters is complete. 

Parameters:
input_bil_folder      -- Path to a folder of .bil files created by a Maxent 
                         model

Outputs:
Creates a new folder `input_mxe` containing rasters converted to the Maxent .mxe 
format.
