beginnings of maec support
now most of the major top level maec items (actions/objects/behaviors/capabilities) are expandable.

well, actually capabilities aren't quite working yet
adding support for basic maec elements
added very basic templates for the different maec objects.

currenly working, but there are some repeated labels/data elements.
main tables adjusted to show contents for maec package's subjects (each row in the table is a subject).

this is just the basic guts (the correct content is not displaying yet)
updated the columns in the maec package's malware subjects table to show the list of (one or more) labels in the first column.  the second column still shows the id.
now maec package's subject have correctly expanding MIOA (malware instance object attributes).

plugging away at getting the rest of the malware_subject data to display correctly...
now showing maec subjects' relationships
starting updates to support maecPackage:Analysis (building the reference item and showing expandable links both work; the actual contents are not there yet)
maec package analysis contents are now showing up.

maec package tools are now expandable with content too.

next up: finding bundles...
added basic support for displaying "finding bundles" and "bundles", but the finding bundle does not properly print out the meta-analysis
added support for maec package action equivalence entries
added preliminary support for process trees (root process and spawned processes)

output needs to be cleaned up (in particular, the list of actions is very verbose and the entire list is displayed by default).
added support for action and objecgt collections (inside Finding_Bundle/Bundle)
first take at supporting maec content embedded inside stix documents

now supports maecInstance:MAEC inside a TTP's behavior.

supports issue #57
deleted duplicate template for maecPackage:Malware_Instance_Object_Attributes that was found in stix_common.xsl (and was identical to the one in stix_to_html.xsl)
updated some of the debugging output to only print when run in debugging mode
for now, do not print "document contents icons" for maec packages/bundles

(this will change when the icons are available)
fixed detection of isRootMaec to also check for root elements for maec packages.

don't display header (aka stix header) for maec documents since there's no corresponding section of the maec doc.
printing the basics of the AV Classificiation table for maec bundles

(not yet printing the body contents)
