gap/basic:
Basic functions to compute with infinite polycyclic groups.
Incorporates everything related to collecting and elements
of pcp groups. Further, includes computation with subgroups
and factor groups of pcp groups as well as homomorphisms.

collect.gi -- methods shared by all collector types
colftl.gi -- from the left collection
colcom.gi -- combinatorial collection
coldt.gi -- deep thought collection
colsave.gi -- save functions for collectors
colrec.gi -- recursive collection (not yet available)
pcpelms.gd/gi -- pcp elements
pcpgrps.gd/gi -- groups of pcp elements
pcppcps.gd/gi -- induced and canonical pcp's of groups
pcppara.gi -- parallel pcp's
pcpexpo.gd/gi -- exponents wrt induced/mod pc
pcpsers.gd/gi -- various series' in pcp groups
grphoms.gd/gi -- group homomorphisms
pcpfact.gd/gi -- factor groups and modulo pcp 's
pcplib.gd/gi -- some generic pcp groups (AbelianPcpGroup etc)
convert.gi -- convert PcpGroup to PcGroup or FpGroup
chngpcp.gi -- change defining pcp (RefinedPcp etc)
orbstab.gi -- finite orbit-stabilizer method
