[openvrml-develop] Recent checkins

[Braden M. <br...@en...>]

Just an update regarding some recent checkins I've made...

I've threatened to do it for some time; now it's done: OpenVRML's stuff
now lives in the OpenVRML namespace. Accordingly, that annoying "Vrml"
prefix has been whacked off a number of our class names.

I've also been rearranging some code into different files; generally,
consolidating multiple classes in a single header/implementation file
pair. A lot of OpenVRML's code has been written under the philosophy,
"one header and one implementation file per class"; this is not a
particularly good strategy for nontrivial C++ library projects. You wind
up with a lot of files; including, most annoyingly, a lot of header
files. Users of the library potentially must use *lots* of #include
directives to get what they need.

So, now, an attempt is being made to sanely organize classes into fewer
files. I've adopted a convention of using all lower-case letters for
file names: since there may be multiple class definitions in a file, it
nolonger makes sense to attempt to match the file name to the class
name.
