Version 0.2
Fixed errors with returning Nana when interpolating low emissivity values.
---
Version 0.2.1
Included methods for loading the database into memory without explicitly specifying the return structure. This allows the calculation to be called from python/IDL without repeatedly loading the database from scratch. Significantly increases the speed while also avoiding memory blow outs in such instances.

Routines identified as "external" are used in this case.
---
Version 0.3.0
Massive revision of the "external" routines. Removed all except the initial data read. Each subsequent routine now checks to see if the apec_data pointer is NULL: if it is, it falls back to the data populated by the initialization routine.

---
Version 0.4.0
Include handling of Z=0, which represents electron-electron bremsstrahlung.
Values from this are multiplied by 1.2, to represent that they depend on Ne^2. not Ne*NH. The assumption is made that Ne=1.2NH (90%H, 10%He, everything else trace)
