Gather non unit tests in a misc folder

[jferard]

There are four fake tests:

• src/test/.../OdsFileWithHeaderAndFooterCreation.java (kind of example)
• src/test/.../OdsFileCreation.java (kind of example)
• src/test/.../ProfileFastODS.java (for profiling)
• src/bench/.../Benchmark.java (for benchmarks) All those files could be in a new src/misc/java folder (a misc would replace the bench one). The first two could have a ...Test.java ending to help running it from maven.

There is an issue when copying all files in src/bench (the name of the dir doesn't matter), because Benchmark.java won't compile without external jars and there is no reason for other files to depend on thoses jars.

Here is a possible structure:

src/misc/bench/com/github/jferard/fastods/Benchmark.java
src/misc/other/com/github/jferard/fastods/...

With the following POM entries:

<profile>
    <id>bench</id>
    <properties>
        <fastods.testSourceDirectory>src/misc/bench</fastods.testSourceDirectory>
    </properties>
</profile>
<profile>
    <id>other</id>
    <properties>
        <fastods.testSourceDirectory>src/misc/other</fastods.testSourceDirectory>
    </properties>
</profile>

The README and the wiki contains some examples that have to be fixed.
