Grid Cell Text Generator

When a grid cell (aka, column) is modified to include HTML such as a link, it will not print when printing the full grid unless you take the additional step of telling the system what to print.

1. An ng-template block in in staff/share/holds/grid.component.html is created to turn the title column into a link to the record page:

<ng-template #titleTmpl let-hold="row">
    <a class="no-href" routerLink="/staff/catalog/record/{{hold.record_id}}">
        {{hold.title}}
    </a>
</ng-template>

<eg-grid-column i18n-label label="Title" [hidden]="true" name='title'
    [cellTemplate]="titleTmpl">
</eg-grid-column>

2. The eg-grid tag should include

[cellTextGenerator]="cellTextGenerator"

3. The grid.component.ts file must include the ability to use GridCellTextGenerator:

import {GridDataSource, GridColumn, GridRowFlairEntry, GridCellTextGenerator} from '@eg/share/grid/grid';

and then inside the class:

cellTextGenerator: GridCellTextGenerator;

4. And then inside ngOnInit - the grid.component.ts file is modified to specify the alternate text that should print out:

this.cellTextGenerator = {
    title: row => row.title
};
