Remove MYMETA files from MANIFEST and repository

These should not be included in the distribution
and the repository because these files are to be
generated and configured by the user of it. So,
also added them in .gitignore list.

See issue #6
Build reasonable META files from Build.PL

Add `no_index` and `keywords` metadata not to
make CPAN users confused. META files will not
be recorded in the source, so list them on .gitignore

See issue #6
Ignore built distribution files from git
Ignore `_share` directory from git

This directory is created at build time
to install shared library and c header files
to per-dist share directory.
Add resource metadatas related to this project

Added `resource` metadatas for URLs of license,
homepage, bugtracker, repository.
State version of META Spec explicitly

Authored META specification is based on 1.4 version
and not compatible to ones with lower or 2.0 version.
Fix #10
[#12] config() returns wrong paths

The library path is made from concatenating per-dist
share directory, and sub-share directory, plus 'lib/',
plus library file name. But the 'lib/' directery was
omitted, so, base directory names and base file name was
correct but its absolute path was incorrect by missing
fragments of each paths.

This commit makes some changes to its API, yet its docu-
mentation is not authored.
Add module documentation as POD

Fixes #5
Release version bumped up to v0.0.1_002
Merge branch 'bump-up'
