tuned output;
tuned comment;
tuned;
tuned iterator;
removed bogus "error" message (it appeared during regular mode of operation)
proper update of text perspective for nodes with changed blobs, which is important to refresh the corresponding command perspective (otherwise it might refer to invalid thy_load commands and cause full execution of the node by the prover);
tuned output;
correct most general type for mutual recursion when several identical types are involved
hide Lifting.invariant from a user completely
more formal Document.Blobs;
removed junk;
proper document blobs for initial edit, which is relevant for loading auxiliary file buffers;
reparse only for actually changed blobs;
tuned signature;
added two examples
A bit of tidying up
more symbol abbrevs to support HOL library maintenance;
more symbols;
store blobs / inlined files as separate text lines: smaller values are more healthy for the Poly/ML RTS and allow implicit sharing;
integrity check of SHA1 digests produced in Scala vs. ML;
tuned signature;
modernized theory setup;
simplified rendering -- no need to over-emphasize "token_range";
amended some slips, rolling back currently dysfunctional export minimimalisation for Scala
