Unit Conversions
The package now does all unit conversions for you. You can change unit systems with
iApi.setUnits()
The default is now "SI", but also available are "cgs", "Cosmology" (M_sun, kpc, Gyr, kms-1) and "Zephyr" (same as before but with kpc Gyr-1).
All values returned, by any function will now be in these units.
Physical coordinates are used throughout (though can be converted using the value for the scale factor at a given time/snapshot from getSimData() ).
**Exceptions: **
-The units used in getSimData are unchanged (boxsize in comoving kpc/h, masses in M_sun and time in Gyr).
-Magnitudes are not converted to luminosities.
-Tracer specific quantities are not converted.

Installing and troubleshooting Quick rundown of what's needed to run the package and some common problems
Unit Conversion All values returned are converted to a user-specified unit system (default SI)
