documentation for install

[millerta]

The build and install instructions in documentation are all out of date.
See https://github.com/lanl/LaGriT/blob/master/documentation/INSTALL.md

Need to update install and related files to the new scripts as described in the README.md file.

[millerta]

Docs build.md updated text and add links to current instructions at README.md and cmake/README.md

Once mac is confirmed as working for V3.3.3, will finish updates to INSTALL.md

[millerta]

install/build instructions are located in various places, mostly old instructions.

How to combine and update install/build instructions?

README.md = current and simple install/build with links to further instructions.

cmake/README.md = advanced install/build instructions should be replace build.md?
change this file to very terse explanation with link to build.md

build.md = from manual, very general and original build instructions - save as old, replace with cmake.
documentation/INSTALL.md = install/build instructions V3.32 and older - remove, put into old build page.
documentation/DEPENDENCIES.md = old instructions for hdf5, zlib, exodus plus CYGWIN for windows - replace with terse explanation and point to new and old build instructions.

Related to the updates to the build pages, update V3.3.3 release notes to include current build and c-fortran code additions.
pages/release_notes/lagrit_release_notes_V3.330.html

There should be a brief description of c-cpp-fortran code guidelines in build

Consider removing /documentation from the repo.
Most the files in that directory were carried over from old version control and the old web pages.
I updated the pages to label as old, and point to newer instructions.
But would be nice to consolidate and remove for a smaller more relevant repo.
Need to figure out exactly which pages are being used in current github io.
