Deprecation warnings while running npm install in mobility-track-nodejs

[harsh183]

When I run npm install in the directory I get the following output.

npm WARN deprecated mongodb@1.4.38: Please upgrade to 2.2.19 or higher
npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
npm WARN deprecated minimatch@1.0.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

I think we should bring all these dependencies up to date rather than find a strange error months later.

Yeah, have to update dependencies.
