Metamorph transformer, which reduces the dimensions of a given dataset.

algorithm can be any of:

• :pca-cov
• :pca-cor
• :pca-prob
• :kpca
• :gha
• :random

target-dims is number of dimensions to reduce to.

cnames is a sequence of column names on which the reduction get performed

opts are the options of the algorithm

metamorph	.
Behaviour in mode :fit	Reduces dimensions of the dataset at key :metamorph/data and stores the trained model in ctx under key at :metamorph/id
Behaviour in mode :transform	Reads trained reduction model from ctx and applies it to data in :metamorph/data
Reads keys from ctx	In mode :transform : Reads trained model to use from ctx at key in :metamorph/id.
Writes keys to ctx	In mode :fit : Stores trained model in ctx under key in :metamorph/id.
