flex shorthand

* u-flexInitial - Sizes the item based on the width/height properties
* u-flexAuto - Sizes the item based on the width/height properties, but makes
them fully flexible, so that they absorb any free space along the main axis.
* u-flexNone - Sizes the item according to the width/height properties, but
makes the flex item fully inflexible. Similar to initial, except that flex
items are not allowed to shrink, even in overflow situations.

Aligning with auto margins

* u-flexExpandTop - Expand top margin to fill remaining space
* u-flexExpandRight - Expand right margin to fill remaining space

All flex utilities can be limited to specific Media Query breakpoints.

* u-sm-flexX - To use at the smallest Media Query breakpoint.
* u-md-flexX - To use at the medium Media Query breakpoint.
* u-lg-flexX - To use at the largest Media Query breakpoint.

`` html


* --sm-viewport
* --md-viewport
* --lg-viewport

When using postcss-custom-media,
breakpoints can be configured using @custom-media. For example:

`css
@custom-media --sm-viewport (min-width:320px) and (max-width:640px);
@custom-media --md-viewport (min-width:640px) and (max-width:960px);
@custom-media --lg-viewport (min-width:960px);
`

Setting flex-shrink in IE10

In IE10 it is required to explicitly set flex-shrink on flex
items,
or use the longhand flex declaration.

In prior versions of utils-flex this was set automatically on all flex items.
Due to issues with specificity this has been removed.

Should you need to apply the fix for IE10 then add a u-flexShrink class
manually:

`html


`
npm install
`

To generate a build:

`
npm run build
`

To lint code with postcss-bem-linter and stylelint

`
npm run lint
`

To generate the testing build.

`
npm run build-test
`

To watch the files for making changes to test:

`
npm run watch
`

Basic visual tests are in test/index.html`.
