Use it as directive instead

[dirkluijk]

This library looks very nice, but why did you choose for a Component instead of a Directive?

What about

<input type="text" ngx-numeric-textbox />

instead of

<ngx-numeric-textbox></ngx-numeric-textbox>

• This way, it is easier to combine with other libs.
• You can directly interact with the input

I ripped your implementation to a StackBlitz and did some improvements:

• Refactored it to directive instead of component
• Removed validation logic, as I think "masking" and "validation" can perfectly be decoupled and applied with template-driven directives or reactive validators
• Removed the need of isNil and isNumber which removes dependency on lodash
• Use key codes from @angular/cdk
• Use coercion from @angular/cdk
• Made it compliant with more strict TypeScript/TSLint settings
• Simplified some code
• Made it locale aware (based on the locale of Numeral.js)
• (Limited) type=number support

If you want, I can donate it back in a PR.
