rrapply 1.2.5

Breaking change: data.frame columns in how = "bind" only include child list names instead of full path names
Added new option how = "names" to recursively update list names
Added new argument options to control default settings for how. Includes control parameters:
- namesep, separator to combine list names in how = "flatten" and how = "bind";
- simplify, coerce flattened list to vector in how = "flatten" and how = "melt";
- namecols, include parent names as columns L1, L2, … in wide data.frame with how = "bind";
- coldepth, override depth layer mapping list elements to data.frame columns with how = "bind"

rrapply 1.2.4

Fixed minor issue with nested data.frames using classes = "data.frame" and how = "recurse"
Removed deprecated arguments feverywhere and dfaslist

Fixed a minor bug classes argument in case of missing f and condition arguments

Added new option how = "bind" to unnest a nested list to wide data.frame
Options how = "flatten", how = "melt" and how = "bind" coerce flat lists to common types
Unnamed list elements receive names "1", "2", … in .xname, .xparents, how = "melt" and how = "bind"
Added pokedex demo dataset
Reorganized source code

Arguments feverywhere and dfaslist are deprecated in favor of classes (instead use classes = "list" or classes = "data.frame")
Added the option how = "recurse" to replace the deprecated feverywhere = "recurse"
Cleaned up source code and fixed several minor issues

Added support for call objects and expression vectors
Added special argument .xsiblings evaluating to sibling list in f and condition

Added new option how = "unmelt" to restore nested list from melted data.frame
Added special argument .xparents evaluating to parent node vector in f and condition

Added new option how = "melt" to return melted data.frame from pruned nested list
Added options feverywhere = "break" for list node aggregation and feverywhere = "recurse" for list node updating
Cleaned up source code and fixed several minor issues
