example: Create multi-trajectory data file
example: Only make minimal changes in config.mk
tica: Updated purge list for commit da5cd4bb
doc: Necessity of column selection before pca

The program fastca cannot exclude columns, so the input
(multi-trajectory-)data must not contain a follower column.
example: Do not change config.mk when updating

So far, updating the example trajectory also reset the configuration.
example: Combine larger variance with faster decay

Consequently, PCA and TICA sort components differently.
information: Negentropy yrange starting at zero
example: Include purge target from main directory
drift: Bugfix to data file selection (downsampling)
langevin: Bugfix to data file selection
config: Documentation of typical projtargets
split: Hash sign for comment on the command line
fields: Suffix .bins for binned data

This makes rule selection more stable so it is
no longer necessary to call make several times.
example: Corrected time step in units of ps
langevin: Rules to call olangevin testmodel programs
fields: Column number determination fixed

Identifiers have been added to comment lines of olangevin programs.
fields: More stable field file selection by suffix
tica: Separate target for rescaling
Merge branch 'master' into tica
