Ensemblegeoseries + MCPCA

[alexkjames]

Adds several new objects to faciliate MCPCA analysis on age uncertain paleo records.

New class include:

• EnsembleGeoSeries - An EnsembleSeries object for GeoSeries objects
• MulEnsGeoSeries - An object to contain multiple EnsembleGeoSeries objects
• MulMultivarDecomp - An object to store and plot the output of MCPCA applied to MulEnsGeoSeries objects

Contains unit tests for all new functions. Also includes a dashboard method for EnsembleGeoSeries objects, and several useful classmethods for generating ensemble and ensemblegeoseries objects from age arrays.

You need to have some example on how to create the object, especially for the classmethod portion

Also, I thought we had agreed on MulMultivarDecomp being `EnsMultivarDecomp', since it's the ensemble part that we emphasize, and Multivar is already Mul. Wow, that was a mouthful...

You're right, I left my post it where I wrote that down in the office and, since I haven't been back since we had that meeting, just winged it. I updated the class name in the most recent commit above this comment (d8fa599).

Great, thank you!
