new test for Overwriting Chunks in RAFileTest

Just a question — do we want to be able to overwrite chunks? If so, are
we ensuring this isn’t happening accidentally by some sort of test?

Also internalDoubleCapacity() now = setCapacity()
Working on Writing test for Node Deletion

Couldn't get program to recongize where deletion of a node was working
Added write/read Large Chunk tests

For RA file test file
Added parameter to setCapacity( int length )

Refactored, all tests still work.
RAFileTest subtleties

Added missing ‘}’ and commented out unneeded statement
Test adding a node for NodeTest

Created an add Node test
ToDo Updated
Fixed bug In MockChunkRandomAccessFile
Refactored RAFileTest

Added a method to protect tests from using same test file name which
returns a new file, deleting the old one.
new RAFile test

testIsFileSizeDoubled() will make ChunkedAccess’s set method call
doubleCapacity().
Updated gitignore so we don't add .dat files
Added RAFile to AVL testing

recreated IntegratedDatabasewithAVLTest and replaced MockChunck... with
RAFile.
Updated AllTests to run all tests
