Added a whole bunch of default values

[sarthakpati]

I am pretty sure there is a better way to do this (for example, having a base Config class under ereg.configurations that reads the sample_config.yaml and populates a baseline Config object, which can then be used in the RegistrationClass class.

However, I unfortunately don't have the kind of time on hand right now to make this change. I would really appreciate it if someone could help me put this together.

Includes #57, so that should/will get merged along with this.

can you open a feature request so we don't lose track of this? @sarthakpati

@sarthakpati currently, unit tests are not passing yet.

once this passes unit tests and is merged, we can merge https://github.com/BrainLesion/eReg/pull/57 to require passed tests before merging, so we don't break ereg again :)

How do you feel about putting default values in a yaml file to create a single source of truth?

Sure, but let's tie it in with #60. Doing yaml I/O in a purely computational class is just clunky.
