ANNZ 2.1.0

- Removed unnecessary dictionary generation from Makefile.

- Changed `std::map` to `std::unordered_map` in main containers of the
`OptMaps()` and `VarMaps()` classes (constitutes a slight performance
boost).

- Nominally, no longer keeping track of the name of the original input
file (stored in the ROOT trees with the name defined in `origFileName`
in `myANNZ::Init()`). This may be switched back on by setting
`glob.annz["storeOrigFileName"]  = True`.

- Added the option to use an entire input file as signal or background
for single/randomized classification, in addition to (or instead of)
defining a cut based on one of the input parameters. In order to use
this option, one muse define the variables `inpFiles_sig` and
`inpFiles_bck`. An example is given in
`scripts/annz_rndCls_advanced.py`.

- Added a bias-correction for randomized regression PDFs. This options
is now active by default, and may be turned off by setting,
```python
glob.annz["doBiasCorPDF"] = False
```

- Other minor modifications.
