Having trouble using this in AoT compiled apps

I'm having trouble using this in our AoT (Ahead of Time compilation) build. AoT is necessary for any Angular 2 app that wants decent production performance.

I think the difficulty is mainly due to absence of *.d.ts files for your library. This causes ngc, when compiling my app, to try to also compile your library's *.ts files. This doesn't work since they're not under rootDir - since it's good practice to keep third party libraries in a separate directory tree from your own app code.

I tried compiling the library with 'npm run ngc', but it seems that is broken in a couple ways.

The "files" target in tsconfig-aot.json references integration-test/ files - that directory doesn't exist in the git clone. I changed files to [ "src/main.ts", "src/datepicker.module.ts"] and got past this issue.

Also noImplicitAny: true is turned on, but the code doesn't pass noImplicitAny rules. Turning that off got me past this issue.

Also the compiler option "declaration": true should be present in order to create .d.ts files. When I turn this on however I get these errors:
Error: Error at /.../Angular-2-Datepicker/src/datepicker.component.ts:331:33: Public property 'dateFormat' of exported class has or is using private name 'DateFormatFunction'.
Error at /.../Angular-2-Datepicker/src/datepicker.component.ts:702:43: Return type of public method from exported class has or is using private name 'ValidationResult'.
Error at /.../Angular-2-Datepicker/src/datepicker.component.ts:722:40: Return type of public method from exported class has or is using private name 'ValidationResult'.

This is because the interfaces are used in the types of public @inputs. Adding "export" before the interface declarations fixed this.

After all this I was able to generate .d.ts files for the library. However I'm still having ngc compilation issues importing the DatepickerModule - but that is probably outside the scope of this issue.

This issue is also resolved in this PR #52
Its in review. If you want it on urgent basis you can use ng-material-datepicker
